The cooling circulation system is used to collect the non-condensable tail gas in the distillation s
Most rectification towers are two-stage condensation. The first stage uses cooling water, mainly condensing the top steam, and the second stage uses chilled water or ethylene glycol, which is mainly used to treat tail gas and remove a small amount of light components. The exhaust gas is condensed. Therefore, the secondary condensation is very small. Generally, a rectification tower (especially in the case of non-condensable gas, such as a vacuum tower, an atmospheric tower with gas dissolved ...

From what aspects should we consider the use of circulating coolers?
Circulating coolers are a popular choice for temperature-critical applications because they provide stable temperature control, constant flow and constant pressure control. Many process heating systems require cooling and heating. For example, many conveyor heating zones have cooling zones. Injection molding requires a lot of heat dissipation. And the reactor is usually jacketed with cold water. There are many ways to cool this type of system, including tap water, tower water, building chille...

Operation method of reaction kettle for circulating heating device
The laboratory single-layer glass reactor equipped with the circulating heating device can place a flask containing the reaction solvent on the inner layer for stirring reaction, and the interlayer can realize constant temperature heating and constant temperature cooling reaction through the circulation of solutes such as freezing liquid, water and heat transfer oil. During the reaction process, the distillation and reflux speed of various solvents can be controlled to observe the correspondi...
View detailsWhat should be paid attention to when placing the thermostat system?
There are certain differences in the size and performance of the high and low temperature thermostat systems produced by different manufacturers. The user needs to pay attention to how it is placed when placing it after purchase, otherwise it will be detrimental to the operation of the high and low temperature thermostat system. The location where the high and low temperature thermostat system is installed should consider the heat dissipation efficiency and whether it is easy to check and mai...

Precautions for the use of chemical refrigeration and heating circulation systems
In chemical production, the reaction will generate heat, which will cause the heat to be uneven. If it is not discharged in time, it will increase the temperature in the kettle and cause danger. The existing heating system of the reactor is relatively simple, and the process of reducing the temperature in the reactor to room temperature takes a particularly long time, and the heat energy cannot be used rationally, resulting in a waste of some resources. However, if the waste heat is released ...
